(Benadryl)?
What is the mechanism of action for 1. antagonizes the effects of H1 receptor sites
diphenhydramine (Benadryl)? 2. Has CNS depressant and anticholinergic effects
(drying--> dry mouth, difficulty urinating,
constipation, changes in vision)
3. It is more effective than nonsedating antihistamines
4. may cause drowsiness
5. works peripherally and centrally
Why would someone take -relief of allergic symptoms
diphenhydramine (Benadryl)?
Nursing Implications (A,I,L,T) for 1. Assessment:
diphenhydramine (Benadryl)? -sedation, urticaria, potency of airway, nausea, bowel
sounds, degree of itching, skin rash, inflammation
2. Implementation:
-when given oral, give with meals or milk
3. Labs:
-may affect allergy testing
4. Teaching:
-avoid OTC cough and cold products while breast
feeding
-avoid driving due to drowsiness
-hard candy or gum for dry mouth
-avoid other CNS depressants while on this med.
,what medication class does non sedating antihistamines
fexofenadine (Allegra), loratadine
(Claritin), and cetirizine (Zyrtec)
belong to?
what is the mechanism of action for -antagonizes the effects of H1 receptors
fexofenadine (Allegra), loratadine -works peripherally to block the actions of histamine
(Claritin), and cetirizine (Zyrtec)? (leads to less CNS adverse effects)
-longer duration of action
why would someone take relief of seasonal allergies
fexofenadine (Allegra), loratadine
(Claritin), and cetirizine (Zyrtec) ?
nursing implications (A,I,L,T) for 1. Assessment:
fexofenadine (Allegra), loratadine -allergy symptoms
(Claritin), and cetirizine (Zyrtec) -lung sounds
-secretions and sputum
2. Implementation:
-maintain adequate fluid intake
-administer with food or milk
3. Labs:
-can cause false skin allergy tests (Allegra)
4. Teaching:
-take medication as directed, if symptoms persist call
healthcare professional
what medication class does adrenergics (oral decongestants)
pseudoephedrine (Sudafed) belong
to?
mechanism of action for -stimulates alpha and beta adrenergic receptors
pseudoephedrine (Sudafed)? -produces vasoconstriction in the respiratory tract
-fight or flight effects
-no rebound congestion
why would someone take -to reduce nasal congestion, hyperemia, and
pseudoephedrine (Sudafed)? swelling in the nasal passages
,Nursing implications (A,I,L,T) for 1. assessment:
pseudoephedrine (Sudafed)? -congestion, bronchial secretions, and lung sounds
-monitor pulse and BP
2. Implementation:
-ensure adequate fluid intake
-administer at least 2 hours before bedtime to
minimize insomnia
3. Labs:
-N/A
4. Teaching:
-take as prescribed
-avoid OTC cold and cough products while breast
feeding
-notify healthcare professional if nervousness, slow
or fast HR, breathing difficulties, hallucinations, or
seizures occur
what medication class does corticosteroid (nasal decongestant)
beclomethasone dipropionate and
fluticasone (Flonase) belong to?
what is the mechanism of action for -locally acting anti-inflammatory and immune
beclomethosone dipropionate and modifier medications that are potent
fluticasone (Flonase)?
why would someone take -anti-inflammatory effects
beclomethasone dipropionate and -seasonal allergies
fluticasone (Flonase)? -decreases symptoms of allergic and nonallergic
rhinitis
, nursing implications (a,I,L,T) for 1. assessment:
beclomethasone dipropionate and -signs and symptoms of hypersensitivity reactions
fluticasone (Flonase)? (rash, pruritus swelling of face and neck, dyspnea)
2. Implementation:
-should be given decongestant 5-15 min before using
a corticosteroid nasal spray
3. Labs:
-need periodic adrenal function tests
4. Teaching:
-take medication as prescribed
-stop if you see signs of anaphylaxis
what medication class does anticholinergic (nasal decongestant)
ipratropium (atrovent) belong to?
mechanism of action for ipratropium -rest and digest effects
(atrovent) -drying effects
-inhibits secretions from glands lining the nasal
mucosa
why would someone take ipratropium want to decrease rhinorrhea
(atrovent)?
nursing implications (A,I,L,T) for 1. assessment:
ipratropium (atrovent) -do they have an allergy to atropine or belladonna
because then they may also be allergic to this med
-rhinorrhea
2. Implementation:
-2 sprays 2-3 times per day if older than 6 years old
3. Labs:
-N/A
4. teaching:
-take medication as prescribed
-contact healthcare professional within 1-2 weeks if
symptoms dont get better

phenylephrine (Neo-synephrine)
belong to?
